HK MR762 A4 16.5" 7.62 NATO Semi-Automatic Rifle

HK MR762 A4 16.5" 7.62 NATO Rifle

The HK MR762 A4 represents the latest evolution of HK-USA's commercial variant of the legendary HK417 platform. Chambered in 7.62x51mm NATO and equipped with a 16.5-inch barrel, the MR762 A4 combines the proven reliability and durability associated with Heckler & Koch with a refined design that's lighter, slimmer, and easier to operate.

At the heart of the MR762 A4 is HK's proven short-stroke gas piston operating system. Unlike traditional direct-impingement systems, the piston design prevents hot combustion gases and carbon fouling from being directed back into the action. This helps the rifle run cleaner for longer periods while reducing maintenance requirements and wear on critical internal components.

The A4 also incorporates an adjustable gas regulator that allows the operating system to be tuned specifically for suppressed or unsuppressed operation. This added flexibility makes the MR762 A4 an exceptionally capable platform for shooters who intend to configure their rifle for different applications.

Fully ambidextrous controls improve usability from either side of the rifle, while the A4's reduced weight and slimmer overall profile make the platform easier to manipulate and employ. The result is a modernized MR762 that retains the durability and reliability of the HK417 family while improving handling and versatility.
